Specification of Lettei's Patent. Patented Sept. 26, 1911.

Application filed December 28, 1908, Serial No. 469,686. Renewed August 7, 1911. Serial No. $12,822.

' clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same.

This invention pertains to a new and useful shingle, molded of any suitable plastic or other material, preferably cement, paraf- 'fin or glass or any other suitable substance,

similar to the above, and the invention has for its object to provide a new and novel device of this design, whereby shingles may be easily and quickly fastened to the skeleton of a building.

A further object of the invention is to provide a shingle having new and novel in- .terengaging means whereby the shingles upon a roof are locked securely in position and means carried by each shingle adapted to exclude or shed water.

A further object of the invention is to provide each shingle with new and novel means to be engaged by novel staples carried by cross bars of the rafters for locking the shingles directly to building skeletons.

This invention comprises further objects and combinations of elements, which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereof will be pointed out by the appended claims.

The features, elements and the arrange ment thereof, which constitute the above entitled invention, may be changed and varied, that is to say, in an actual reduction to practice, with the understanding that the changes and variations accruing from said reduction to practice are limited to the scope of the appended'claims.

To obtain a full and correct understanding of the details of construction, combinations of features, elements and advantages, reference is to be had to the hereinafterset forth description and the accom anying drawings in connection therewith, w erein-'- Figure 1 is a perspective view of a portion of a roof, showing a plurality of shingles fastened thereto. Fig. 2 is a sectional view on line 2-2 of Fig. 1, showing the manner of interengagement of the shingles. Fig. 3 is a detail view, showing the means for fastening the shingles to the cross bars of the rafters. Fi 4 1s a detail perspective view of the outer face of a shingle, and also showing another shingle. Fig. 5 is a per-- spective view of the shingles, showing the under face thereof. Fig. 6 is a detail view of a modified form for holding the shin les to a metallic cross bar of the rafters. ig. 7 is a detail view showing the manner in which the fastening means or staples 3 are formed.

In regard to the drawings, wherein similar reference characters lndlcate corresponding parts in the several illustrations, 1 designates the rafters of a skeleton of a building, transversely of which are disposed the cross bars and members 2, which are provided with fastening means or staples 3, by which the shingles are held to the said skeleton.

The shingles, when fastened to the skeleton, are designed to overlap and also to break joints'in the usual manner, as shown clearly in Fig. 1 of the drawings. The shin' gles are designated by the numeral 4, the lower outer faces of which are convex, as will be seen by observing the numeral 5, while the under surface, opposite to surface 5, is concave, as at 6, as shown clearly in the drawings.

The upper portion or half of each shingle is somewhat tapered, as shown, and provided on the corners thereof are grooves 7, which are designed to receive'the angularly disposed ribs 8 upon the under side of the adjacent or overlapping shingle, as shown clearly in the drawings. Between the grooves 7 are grooves 9, which are designed to be filled with a filling, welt, lime or other substance, saturated with any suitable waterexcluding or shedding material or solution, I

cured to said crossbars, and the free portions of said metal are coiled about one another, as shown in the drawings, and in such wise as to form lateral projecting lugs 11,

. sions 12 upon the shingles, which are formed side of each shingle is provided with a .gether with thesimplicity' thereof, will be the purpose o f which is to engage the depresat the ends of the grooves 7, as will be clearly seen in the drawings.

In Fig. 6, a modified form of fastening means is illustrated, and in this form the loop 10 is shaped in such a manner as to engage the grooved portion of the metallic cross bar, as'shown in said Fig. 6, and when the lugs 11 of the fastening means are engaged with the said'depressions, the shingles are'securelyheld to said metallic rafters, as clearly shown in the drawings. .The under .strengtheningrib 13 which extends from the apex of the'ribs 8 to the upper end of the shingle, as shown clearly in the detail view of the drawings.

From the foregoing, the essential features, elements and the operation of the device, to-

clearly apparent.

Having thus fully described the invention, what'is claimed as new and useful is 1. The combination of a plurality of molded shingles, each comprising angularly disposed edges-at their upper portions having angular y' disposed grooves adjacent the Q mo ses having upon their under faces angularly disposed ribs to engage the grooves of theadjacent shingles and provided with a central longitudinal strengthening rib, said shingles having upon their: outer faces a pair of grooves curved outwardly at their lower ends provided with a saturated water-ex eluding filling, said shingles having depressions adjacent the lower ends of the firstnamed grooves to receive shingle fastening devices.

2. The combination of a roof skeleton comprising rafters and transverse bars, of a plurality of molded shingles having interengaging means and provided with short grooves adjacent their meeting side edges, said transverse bars having grooves, and fastening means to engage the grooves of the bars and disposed between the adjacent side edges of the shingles and provided with oppositely arranged lugs to engage the short grooves-of the shingles, as specified;

name to this specification in the presence of two subscribing witnesses.
